President Barack Obama's joint press conference with Canadian Prime Minister Justin Trudeau on Thursday had all the hallmarks of a torch-passing between progressive leaders.

Obama repeatedly touted his younger counterpart's work on climate change and referenced the liberal values he and Trudeau share. He even gave Trudeau, 44, advice on coloring his hair when the stress of his office turns it gray.

The Evangelical Environmental Network is just what it sounds like: a ministry of evangelicals, mostly Republicans, who believe climate change is dangerous and worth fighting.

"I’m a Republican, and our organization is designed to reach out to evangelicals who are, by and large, conservative politically as well," Rev. Mitchell Hescox, president of EEN told CQ Roll Call last week.

Pope Francis is expected to advocate for issues such as immigration and climate change in his address to Congress Thursday, much to the delight of most Democrats. But for all the excitement over issues they agree with, Inhofe said he hasn't noticed a Democratic rush to adopt some of the Catholic Church's other, more long-held, policies. Senate Democrats blocked a bill Tuesday banning abortions beyond 20 weeks and are likely to oppose a continuing resolution that diverts money from Planned Parenthood over an abortion-related controversy . And that has the Oklahoma Republican calling out hypocrisy.

Senate Republicans were swept into power vowing to fight the White House's "war on coal," but at least one says they need a broader message than "no" in 2016.

“I think there will be a political problem for the Republican Party going into 2016 if we don’t define what we are for on the environment,” Sen. Lindsey Graham, R-S.C., said. “I don’t know what the environmental policy of the Republican Party is." Graham, who worked on a climate change proposal in 2010 with Sen. John Kerry, D-Mass., suggested that what worked in the midterms might not work the next time around.

Sen. Roy Blunt’s office sent out a press release with a spectacular math fail that made the new EPA regulations on power plants look far more expensive than even the U.S. Chamber of Commerce’s own study suggests.

“The study reveals that U.S. consumers would pay almost $290 billion more for electricity between 2014-2030, an average of $17 billion more per year,” the release reads, before going off the rails.

In the second installment of The Purple Network's "Opinion Duel," Roll Call Editor-in-Chief Christina Bellantoni moderated a discussion with Charles C. W. Cooke, from National Review and The Nation's Zoë Carpenter over the widely debated topic of climate change. Carpenter and Cooke discussed whether anything is being done to address climate issues and how this debate has shifted the political landscape. They also detailed the industry's "big money" in politics and how it sways popular opinion.
